BACKGROUND Technical Field

The present disclosure relates to transmission schemes of radio signalsin wireless communication systems, and in particular to a method and adevice for multi-antenna transmission.

Related Art

Massive Multi-Input Multi-Output (MIMO) becomes one research hotspot ofnext-generation mobile communications. In the massive MIMO, multipleantennas experience beamforming to form a relatively narrow beam whichpoints to a particular direction to improve the quality ofcommunication. The massive MIMO can also form different directionsthrough multiple antennas to serve multiple users simultaneously,thereby forming Multi-User MIMO (MU-MIMO), and thus improving thethroughput of the massive MIMO system and reducing the delay oftransmission.

In 3GPP New Radio discussion, there is some company proposing toincrease the robustness of transmission using a relatively wide beamtransmitting Physical Downlink Control Channel (PDCCH) and to increasethe Signal-to-Noise Ratio (SNR) using a relatively narrow beamtransmitting Physical Downlink Shared Channel (PDSCH). There is alsosome company proposing to use the PDCCH to cross-slot indicate thetransmission beam of the PDSCH, so as to solve the problem of delaybetween a User Equipment (UE) acquiring the transmission beam of thePDSCH from the PDCCH and conducting PDSCH receiving using the beaminformation indicated by the PDCCH.

SUMMARY

In one embodiment, the inventor finds through research that cross-slotbeam indication would result in reduction of dynamic of beaminformation, increase of overhead of control signaling, reduction ofdynamic of scheduling, and other problems. A UE with high processingcapacity can decode the PDCCH in a short time to obtain beam informationthat is used for receiving the PDSCH that is in the time slot of thePDCCH, and adjust a receiving beam to receive a multicarrier symbol inwhich the PDSCH is located. However, the delay in PDSCH transmissioncaused by decoding PDCCH would result in underutilization of systemresources.
